Dynamics 365 CRM Online-插件仅每隔一次触发执行更新

Question

更新 我从该论坛以及Dynamics论坛中获取了一些信息，并且我的代码可以正常工作。代码中的主要问题是我只查看了preImage，但是在大多数情况下，这三个值之一将被更新，这意味着我无法针对该特定字段的preImage。我更改了逻辑以使用Collection属性（更新值）（如果已更新），但是使用PreImage值（如果未更新）-这使代码起作用，并且每次都会触发更新-不再需要触发插件两次！这是更新后的代码-比原始代码更有效，更简洁（向下滚动以查看旧的/无效的代码）。我还添加了一些评论，以使其更易于理解。感谢所有人的帮助（在SO和Dynamics论坛上都是如此！）

原始帖子 再回来吧！昨天，我意识到我不使用PreImage来获取未包含在更新的属性集合中的值的错误-SCORE！现在，插件可以工作，但仅在我触发插件时每隔一次就可以工作。

因此，似乎插件实际上正在启动（我可以在“设置”>“插件配置文件”中看到插件配置文件），但是没有执行我需要的更新，直到第二次触发插件为止。这似乎发生在我正在监听的所有3个属性上，并且每个属性都需要更新两次（例如，如果我更新了属性1，则插件不会更新我的值，如果我随后更新了属性2，插件仍然不会更新我的值，直到再次重新更新属性1或属性2为止）。在我分析/调试代码并逐步执行代码时，我可以看到if语句被命中，并且更新了实体字段的代码行也正在执行-但由于某种原因，它没有设置值（ CLIENT_nteexceeded = true或false），直到我第二次触发它为止。如果它根本不更新实体记录值，那将更有意义，而且我缺少某种类型的“更新”消息（我曾使用过service.Entity.Update（），但似乎没有应用于此插件）

我对CRMDEV还是一个新手，所以请原谅这个愚蠢的问题。对我来说，这似乎是一个非常愚蠢的问题，这肯定是我所缺少的小事情。关于为什么这迫使我两次触发代码以执行更新的任何想法？

这是插件步骤的配置。这三个过滤器属性是代码中引用的属性。同样，插件工作正常，只是不会每次都更新记录。

Answer 1

我将帮助您了解CRM执行管道的工作方式。然后，您可以借助trace / Audit / profiler进行故障排除，以找出失败的地方。

基本上，您是在预验证/预操作阶段中，在数据库事务处理之前，截获CRM CRM中发生的service.Update()平台调用。然后根据业务需要进行数据处理，并在目标实体本身中设置额外的属性值。这避免了另一个显式的额外service.Update()调用和返回循环死锁。

如果有任何异常，则表示您正在登录跟踪并抛出该异常。我建议将其更改为InvalidPluginExecutionException，您将在UI弹出窗口中看到它。这将回滚事务，这意味着将不会保存数据。

此外，为了更好地理解-记录每个条件语句，变量值等，以查看发生问题的确切跟踪日志。

Answer 2

更新/答案我从该论坛以及Dynamics论坛中获取了一些信息，并且我的代码可以正常工作。代码中的主要问题是我只查看了preImage，但是在大多数情况下，这三个值之一将被更新，这意味着我无法针对该特定字段的preImage。我更改了逻辑以使用Collection属性（更新值）（如果已更新），但是使用PreImage值（如果未更新）-这使代码起作用，并且每次都会触发更新-不再需要触发插件两次！这是更新后的代码-比原始代码更有效，更简洁（向下滚动以查看旧的/无效的代码）。我还添加了一些评论，以使其更易于理解。感谢所有人的帮助（在SO和Dynamics论坛上都是如此！）
